Medical endoscope system is mainly composed of equipment system and surgical instrument system. Surgical instrument system is mainly classified by department or operation name. There are endoscopes, special instruments, surgical instruments and disposable surgical consumables used in various departments. I won't give a detailed introduction here. Next, we mainly discuss the structure of the equipment system.

在设备系统中我们通常可以分为：摄像显像系统，影像记录系统，光源系统，人工气腹系统，液体加压系统，电凝电切系统，动力消融系统，冲洗吸引系统等等。

In the equipment system, we usually can be divided into: camera imaging system, image recording system, light source system, artificial pneumoperitoneum system, liquid pressure system, electrocoagulation system, dynamic ablation system, flushing and suction system, etc.

（1）摄像显像系统：该系统包括显示器和摄像机。显示器有常规的CRT和液晶两种，摄像机有单CCD和3CCD两种。现在使用客户多是液晶显示器配3CCD摄像器。

(1) Camera imaging system: the system includes display and camera. There are two kinds of displays: CRT and LCD, and two kinds of cameras: single CCD and 3CCD. Now most of the customers use LCD with 3CCD camera.

（2）影像记录系统：现在很多医院都选择以电脑为基础的图文工作站。该系统分两部分：电脑硬件和图文采集软件。

(2) Image recording system: now many hospitals choose computer-based graphic workstation. The system consists of two parts: computer hardware and image acquisition software.

（3）光源系统：又称冷光源。冷光源灯泡中充有卤素和氙气两种，其输出功率为70-400W。现在300W氙光源是主流的产品。其突出特点是光线强烈，色温5600-6000k，与太阳光类似，涵盖了从紫外线到红外线的整个波段。

(3) Light source system: also known as cold light source. The cold light bulb is filled with halogen and xenon, and its output power is 70-400w. Now 300W xenon light source is the mainstream product. Its outstanding feature is strong light, color temperature 5600-6000k, similar to sunlight, covering the entire band from ultraviolet to infrared.

（4）人工气腹系统：将气腹机与二氧化碳钢瓶连接好，并旋开钢瓶上的阀门，然后开启气腹机，根据手术的需要，选择压力预设值，当腹腔内压力超过或低于设定值时，全自动二氧化碳气腹机可自动开始或停止注气。

(4) Artificial pneumoperitoneum system: connect the pneumoperitoneum machine with the carbon dioxide cylinder, loosen the valve on the cylinder, and then turn on the pneumoperitoneum machine. According to the needs of the operation, select the preset pressure. When the intra-abdominal pressure exceeds or falls below the set value, the automatic carbon dioxide pneumoperitoneum machine can automatically start or stop gas injection.

（5）液体加压系统：关节泵、膨宫泵和膀胱泵等系统主要是用于通过液体加压成腔，然后再通过器械在腔体内进行手术。

(5) Liquid pressure system: Joint pump, uterine distention pump and bladder pump are mainly used to form cavity by liquid pressure, and then operate in the cavity by instruments.

（6）电凝电切系统：在普通开放性手术中和微创手术中都常使用高频电刀。

(6) Electrocoagulation and electrosurgical resection system: high frequency electrotome is often used in common open surgery and minimally invasive surgery.

（7）动力消融系统：在鼻窦镜和关节镜手术中多会使用的是动力刨削系统和离子消融刀，这两种设备虽然价格不菲，但是它们却大大地缩短了术中时间和降低了手术风险。

(7) Dynamic ablation system: dynamic planing system and ion ablation knife are often used in endoscopic sinus surgery and arthroscopic surgery. Although these two devices are expensive, they greatly shorten the operation time and reduce the operation risk.

（8）冲洗吸引系统：设备冲洗流速少应达到1L/min。

(8) Flushing suction system: the equipment flushing flow rate should be less than 1L / min.
